CAUTION:
For more detailed information concerning the mower ask your dealer
or manufacturer.
2. INTRODUCTION
 This operator’s manual should be considered as the basic mower’s equipment. If the mower is
handed over to another operator, it should be in working condition and given away along with
operator’s manual and it’s other basic equipment.
 Operator’s manual is attached to every machine in order that the operator can familiarize himself
with design, working principles, service and adjustment of the mower. The user of the mower
should be familiar with common safety rules and procedures.
 The mower is manufactured according to international safety rules.
 Compliance with the warnings in this operator’s manual will ensure safe operation.
 Please contact your dealer if you have any queries relating to the operation and service of the
mower.
 Operator’s manual remains part of mower’s equipment.
GENERAL WARNING
When operating the mower please comply with the
warnings and safety regulations shown throughout this
manual by this safety alert symbol.

CAUTION:
Operation of the mower before reading the operator’s manual carefully
as well as operating by the unauthorized staff, especially by children, is
strictly forbidden.
3. PROPER USE
a) mower without conditioner
SaMASZ front disc mower is designed for mowing standing grass on meadows and in stone free
fields. It is a machine for hay and green fodder production. When the high grass prevails, the first and
the second cut should be mowed at the height level - 6-7 cm, but when the grass grows low – at the
height level - 5 cm. The last cut should be mowed a little bit higher – 7-8 cm above the ground.
b) mower with tine/roller conditioner
SaMASZ front disc mower with tine/roller conditioner is designed for mowing standing grass on
meadows and in stone free fields. It particularly concerns mowers with roller conditioner, because they
tolerate stones only up to few centimeters. If a mower comes across a bigger stone, tractor-mower set
must be stopped and the stone removed, because it may lead to serious damage. It is a machine for hay
and green fodder production. Tine/roller conditioner provides effective conditioning and accelerates
drying of the forage. Roller conditioner is recommended in case of fragile crops like lucerne (alfalfa).
It reduces leaf loss to an absolute minimum. When the high grass prevails, the first and the second cut
should be mowed at the height level - 6-7 cm, but when the grass grows low – at the height level - 5
cm. The last cut should be mowed a little bit higher – 7-8 cm above the ground.
CAUTION:
Use of the mower for other purposes than the above mentioned
is forbidden. Different use than the above mentioned will be considered
as improper and may lead to revoking of the warranty. Mower should be
used, operated and repaired only by people familiarised with its detailed
specifications and with safety rules and regulations. Wilful changes of the
mower will lead to revoking of the warranty.
Mower KDF 260 works properly with tractors (class 2,0 and power from 70 HP ). Mower KDF 300
works properly with tractors (class 2,0 and power from 80 HP ). Mower KDF 260S works properly
with tractors (class 2,0 and power from 90 HP). Mower KDF 260W works properly with tractors (class
2,0 and power from 90 HP). Mower KDF 300S works properly with tractors (class 2,0 and power from
100 HP). Mower KDF 300W works properly with tractors (class 2,0 and power from 100 HP).

(Decsription of Fig. 3a.)
Drive from tractor’s rpm is transmitted through PTO shaft, intersecting axis gear (4), cutterbar drive
shaft (6) and intersecting axis gear (5) to the cutterbar (3). On the cutterbar there are discs with two
knives each. The extreme discs have additional forming drums. Cutterbar is connected to the main
frame (2) along with suspension frame (1). On the suspension frame there is mower’s triangle, which
is designed to connect the mower to tractor’s front 3-point linkage. Over the cutterbar there are safety
guards (10).

CAUTION:
Any spare part used for repair of the mower should have all warning

Optimum work parameters
1. Inclination towards the front 4÷5 degrees which stands for 6÷7 cm of mowing height.
2. Operation speed ≥10 km/h.
3. PTO rpm = 900÷1000 rpm. PTO rpm > 1000 may cause stripes of uncut grass
between the discs.
4. Tractor’s rpm (max. moment – economical fuel consumption 1600÷1800 rpm).
High and inclined grass.
5. Highten the cutterbar’s inclination to – H = about 4 cm.
6. Operation without cutterbar’s inclination may cause winding of grass on the forming
drums.
7. Speed up to V ≥12 km/h. (the faster – the better)
8. Do not take turns in the mowed grass.

5. OPERATION
5.1 Attaching the mower to the tractor
Mower KDF 260 works properly with tractors (class 2,0 and power from 70 HP ). Mower KDF 300
works properly with tractors (class 2,0 and power from 80 HP ). Mower KDF 260S works properly
with tractors (class 2,0 and power from 90 HP). Mower KDF 260W works properly with tractors (class
2,0 and power from 90 HP). Mower KDF 300S works properly with tractors (class 2,0 and power from
100 HP). Mower KDF 300W works properly with tractors (class 2,0 and power from 100 HP).
CAUTION:
Manufacturer is not responsible for mower’s damage, if it is caused by
improper mounting.
Unmounting of the mower may cause the following damages:
-bending of mower’s guards by the tractor,
-damage of PTO shaft,
-damage of the gear and other parts of the mower.
During operation check mounting of the mower.
The mower is mounted on the tractor’s triangle which is connected to the tractor’s front 3-point
linkage (the tractor’s triangle cat. II is NOT a part of standard equipment – it can be ordered from
SaMASZ as optional extra equipment).When the triangle is connected to the tractor’s 3-point linkage,
adjust it (by means of upper link) in parallel to the mower’s triangle, lift the 3-point linkage until it
locks in, check the space between 1triangle’s hook and pawl 2(Fig. 7a.), block the hook 1with cotter
pin ∅4 2(Fig. 7b.), adjust the space between the frame suspension and a rubber safety bumper to
about 150 mm (Fig. 7), regulate and mount support chains, block them with cotter pins according to
5.3.After the mower has been attached to tractor, check the balance and steerability of tractor-mower
set. To do it, weigh the set and after that drive on the weigher with only the rear axis of the tractor (the
mower must be in transport position – lifted upwards). If the pressure on the rear axis is at least 20%
of the whole set’s pressure, it means the set is stable. If not, the rear axis should be balanced.
